CVE-2020-11026
Estado: ModificadaMedia (5.4)—
En las versiones afectadas de WordPress, los archivos con un nombre especialmente diseñado cuando se cargan en la sección Multimedia pueden conllevar a una ejecución de script al acceder al archivo. Esto requiere un usuario autenticado con privilegios para cargar archivos. Esto ha sido corregido en la versión 5.4.1, junto con todas las versiones afectadas anteriormente por medio de una versión menor (versiones 5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
- Puntuación base: 5.4
